The interaction between a power system and a wind-farm can be studied using either a simplified ‘aggregated’ or a complex ‘detailed’ model. The detailed-model results compare well with the actual, therefore, provided that both models have similar dynamic characteristics, the aggregated model...
The main goal of this work is to develop specific procedures for implementation in wind turbine simulators designed especially for small machines. Using blade element methodology, we establish procedures for the torque and power characteristics of a small wind turbine, where some physical...
In this article, a fuzzy PI gain scheduler for a vector controller is developed to control a doubly-fed induction generator used in a variable speed wind turbine. Effects of both main flux and leakage flux saturation are considered in the machine model in order to obtain more realistic results....
This article describes the development of the Musgrove Vertical Axis Wind Turbine (VAWT) concept, the UK ‘Carmarthen Bay’ wind turbine test programme, and UK government's wind power programme to 1990. One of the most significant developments in the story of British wind power occurred during the...
Accessories, such as end plates, deflecting plates, shielding and guide vanes, may increase the power of a Savonius rotor, but make the system structurally complex. In such cases, the rotor can develop a relatively large torque at small rotational speeds and is cheap to build, however it...
A small test software-model for the transmission system containing a number of central power plants, consumption centres, local wind turbines and a large offshore windfarm has been implemented in the simulation tool Powerfactory (DigSilent). This model demonstrates the interaction between...
